SPECIFICATIOIlfmming part of Letters Patent No. 316,722, dated April 28,1885.

Application filed October 16, 1884. (No model.)

.To all whom it may concern.-

Be it known that we, HENRY B. BALOH and FRANK BURTT, citizens of theUnited States, residing at Kalamazoo, county of Kalamazoo, State ofMichigan, have invented a new and useful Grain-Cleaning Mill, of whichthe following is a specification.

This invention has for its object certain improvements in that class ofgrain-cleaning mills in which the cleaned grain is elevated for thepurpose of bagging.

The most important result attained by this invention is the locating ofthe elevatingcups in the center of the rear portion of the mill. Otherresults and the points of utility will appear in the following detaileddescription.

In the drawings forming a part of this specification, Figure 1 is avertical section of the mill on the dotted line :0 w in Fig. 2. Fig. 2is a front View of the internal construction in the rear portion of themill. Fig. 3 is a detail of Fig. 1, enlarged, hereinafter described andpointed out by letters, Fig. 4, an elevating-cup in perspective; andFig. 5 is a broken detail of parts in Figs. 1 and 2, enlarged, lookingfrom a point at the right hand in Fig. 1, hereinafter described andreferred to by letter.

Referring to the drawings, B is the frame inclosure of the mill, similarin most respects to that of all fanning-mills. We make thefan in twoparts, separating the wings D D at the center, and leaving sufficientspace to centrally locate the elevating-cups a a and endless belt a, towhich they are connected at an oblique angle in the fan-chamber of themill. The upper rear wall of the mill-casing is provided with a centralopening, Fig. 1, which may be roofed over, as at S, said roof, togetherwith the bridge 6, forming a spout to deliver the grain into a bag heldthereunder by any suitable means. Near this opening in the millcasing isa revoluble shaft, 2, having suitable bearings, the latter not hereshown. To this shaft are rigidly secured, side by side, twosprocket-wheels, o e. The fan-shaft r is provided with a rigidly-securedsprocket-wheel, f. The sprocket-wheels o f carry a sprocketbelt, a, andthe sprocket-wheel e and the idler n at the lower end of theelevatingapparatus carry the sprocketbelt c, to which belt the ele:vating-cups a a are connected. These sprocket-wheels and belts arepreferably made as shown; but, of course, if other styles of belts areused, the belt-wheels o e f will be made to conform thereto.

When the fan-shaft r is revolved by turning the crank h, geared thereto,the belt 0, with its cups a a, is carried around the belt- Wheel e andidler a, ascending over the shaft 0 and descending below it. An inclinedwall, i, joins the bridge 6 at the upper end, and terminates at thelower end in a tray, P, beneath the lower end of the incline sieve r,the latter being the sieve which in other mills conveys the grain to thelower rear delivery, discharging the grain onto the floor. The positionand arrangement of the cups (1 a are such that the grain runs off thelower end of the sieve 7* into the cups, and is discharged out of thecups through the opening at the upper end in the wall of themill-casing,said cups representing in form four sides of a cube, Fig. 4., with thefree corners cropped off, if desired. To illustrate, supposing the millto be in motion, referring to Fig. 1, the cup at the lower end of thesieve r is receiving grain, and the upper cup, which has passed throughthe opening,

forms part of the discharge-spout, as before described. It will beobserved that after said cup has emptied its contents it passes onaround the sprocket-wheel e, and enters the opening again between saidwheel and the upper end of the bridge 6'. Thus while one cup isdischarging the grain the cup next beyond has just entered the openingand presented its straight back wall, forming a temporary eX- tension tothe bridge 6', preventing any grain from entering the opening andrunning down the incline wall t.

It will be understood that the shoe, (not here shown,) with which thescreens and sieves of the mill are connected, is connected by suitablemechanism with the fan-shaft, as in nearly all fanning-mills, so thatthe one crank it performs the whole operation in fanning, shaking, andelevating.

A mill thus internally provided with an is discharging grain onto thebridge c',wl1ich elevating apparatus is no more cumbersome or bulky thanthe old common style of mills. The height of the discharge-opening fromthe floor nicely corresponds with the height of a bag. The upper rearwall of the mill-casing forms a suitable and convenient support for theroof and bridge composing the spout, and a proper support to the bag.The addition of but a few simple elements is necessary to those alreadyin fanning-mills.

The wings of the double fan are set obliquely to each other, as atD D,Fig. 2, in order to throw wind toward the space between the fanwings inits outward passage, thus compen sating for the absence of the fan-wingsin said space.

. Having thus described our invention, what we claim as new, and desireto secure by Letters- Patent, is-- 1. A grain-cleaning mill consistingof a casing provided with a grain-discharge in its lower portion, andwith an opening through its upper rear wall, means within the casing forcleaning grain, and a grain-elevator extending from said grain-dischargeto the opening through said upper rear wall, substantially as set forth.

2. A fanning-mill consisting of a casing provided with an openingthrough its upper rear wall, suitable screens, a double fan, and anendless belt bearing elevator-cups, and ex tending from the lowergrain-discharge from the screens up between the fans to said opening,substantially as set forth.

ing through the upper rear wall of the eas- 3. A grain-cleanerconsisting of a casing, means therein for cleaning the grain, saidcasing having a grain-discharge in the lower portion and an openingthrough its upper rear wall, a slanting grain-bridge at the lower 40side of said opening, and an endless belt carrying elevator-cups, thebacks thereof being constructed and arranged to form temporaryextensions to said grain-bridge, substantially as set forth.

4. A fanning-mill consisting of a casing having an opening in the upperrear wall, screens, a double fan, a shaft having twosprocket-wheels nearsaid opening, an idler near the grain-discharge from the screens, asprocket-wheel on the fan-shaft between the fans, a sprocket drive-chainon .the wheel between the fans and the wheel over it on the upper shaft,and a sprocket-belt bearing elevator-cups on the idler and on the otherwheel on the upper shaft, substantially as set forth. r

In testimony of the foregoing we havehereunto subscribed our names inpresence of two witnesses.
